Avoiding Fibonacci-like sequences
@user17348 that's a good point, and is actually what I was really looking for. I thought I'd ask about this as an intermediate case. |

Euclidean embedding of a graph based on 1-ring neighborhood distances only
"If $l_{ij}$ were a complete matrix, multidimensional scaling would yield an embedding into $\mathbb{R}^3$, such that Euclidean distances correspond to $l_{ij}$.". I'm not sure why this is true. There are plenty of graphs that cannot be embedded (I assume you mean isometrically) into 3-space. |

How to estimate the entropy of a distribution on a power set?
It's not relevant for computing the entropy that the power set structure is useful for applications. Since you haven't indicated that the power set structure has any constraints, then as @usul points out it's equivalent to having an arbitrary collection of integers in a larger set. |

Does high min degree and high odd girth imply near bipartiteness?
I'm confused. How is a graph bipartite if it has any odd cycle ? |

Integer point in a non-empty polytope
This problem is NP-complete, so you're unlikely to find a good algorithm without more info about how the polytope is constructed. |

Distance measure for noisy $SE(3)$ transforms
Are you trying to define a new distance on the underlying space or a distance between a point and its distribution of transforms ? |

Similarity of weighted graphs
Treating a weighted graph as a matrix has the problem that you lose permutation invariance (or that you have to explicitly encode permutation invariance into your distance function). |

Is this function of a matrix convex?
But $A$ is not symmetric (the question requires symmetric matrices) |
